Abstract
Description
Technical Field
[0001] This utility model relates to the field of status indicator fixing technology, and in particular to a quick-change clip for instrument status indicators. Background Technology
[0002] In industrial production and equipment maintenance, instruments serve as crucial data acquisition and monitoring devices. Their surface tag status indicators, such as "Running," "Under Maintenance," "Isolated," and "Pending Calibration," indicate the equipment's status. Operators can quickly switch between the corresponding status tags based on the equipment's condition. These status tags are important indicators of equipment status and are widely used in chemical, power, and metallurgical industries. Currently, there are two main methods for fixing instrument tag status indicators: one is to directly attach the status indicator to the instrument housing using fasteners such as screws and rivets; the other is to use an adhesive structure to attach the status indicator to the instrument surface.
[0003] For rivet (or screw) fixing, the fasteners need to be removed first when installing the status indicator, which is a cumbersome process. In addition, some instruments may need to replace the status indicator in order to obtain accurate parameters. At this time, it is necessary to use tools to remove the rivets (or screws) one by one and then use the rivets (or screws) to install the new status indicator. Repeatedly removing the fasteners can easily cause the rivet holes of the instrument housing to be enlarged (or the threads to be stripped), which will result in the subsequent status indicator not being able to be firmly fixed.
[0004] While adhesive mounting is convenient for initial installation, the adhesion between the status indicator and the instrument surface gradually weakens over time and with changes in ambient temperature and humidity. This is especially true in industrial environments with high temperature, high humidity, or corrosive gases, where the adhesive layer is prone to aging and failure, leading to the status indicator falling off. Furthermore, when replacing the status indicator, it is necessary to clean off any residual adhesive from the old one. This cleaning process may scratch the coating on the instrument housing, affecting the appearance and protective performance of the equipment.
[0005] Therefore, it is necessary to provide a new quick-change instrument status indicator to solve the above-mentioned technical problems. Utility Model Content
[0006] To solve the above-mentioned technical problems, this utility model provides a quick-change clip for instrument status indicators.
[0007] The quick-change clip for the instrument status indicator provided by this utility model includes:
[0008] Mounting frame;
[0009] The mounting frame has an insertion cavity that penetrates the top frame surface of the mounting frame. The front plate of the insertion cavity has a through cavity that communicates with the insertion cavity, and a transparent plastic plate is fixedly embedded in the through cavity. The rear plate of the insertion cavity has several evenly distributed mounting grooves.
[0010] Each of the mounting slots is equipped with a contacting component for a pressing status indicator, which securely abuts the status indicator inserted into the insertion cavity against the transparent plastic plate.
[0011] The abutting component includes a sliding column, which is installed in the mounting groove and slidably connected to the mounting groove. A rotatably connected steel ball is installed in the hemispherical groove opened at the head of the sliding column, and a spring is provided in the mounting groove.
[0012] Preferably, one end of the spring is fixedly connected to the inner wall of the mounting groove, and the other end of the spring is fixedly connected to the insertion end of the sliding column.
[0013] Preferably, the steel ball abuts against the inner surface of the transparent plastic sheet.
[0014] Preferably, the bottom frame of the mounting frame has several drainage holes that communicate with the insertion cavity.
[0015] Preferably, the front panel of the mounting frame has a recessed arc groove.
[0016] Preferably, the mounting frame has multiple symmetrically distributed fixing holes on both sides.
[0017] Preferably, a rubber pad is fixedly fitted to the back of the mounting frame.
[0018] Compared with related technologies, the quick-change clip for the instrument status indicator provided by this utility model has the following advantages:
[0019] This invention only requires the mounting frame to be firmly fixed to the instrument's mounting area initially, and then the status indicator is installed into the insertion cavity of the mounting frame by insertion. The entire status indicator installation process takes only a few seconds, greatly improving replacement efficiency. It is especially suitable for installation scenarios with dense instruments or limited space. Several evenly distributed abutment parts can form multi-point uniform pressure on the status indicator, ensuring that the status indicator fits tightly against the transparent plastic plate and preventing the status indicator from shifting due to vibration or impact. At the same time, this structure does not require drilling holes in the status indicator, avoiding problems such as rivet hole enlargement (or thread stripping) and shell damage when replacing the status indicator later. It can be repeatedly disassembled and used, and its long-term reliability is significantly improved. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0028] Please see Figures 1 to 5 This utility model provides a quick-change clip for an instrument status indicator, which includes a mounting frame 1 and an abutting component 2.
[0029] In the embodiments of this utility model, please refer to Figures 1 to 5 The mounting frame 1 has multiple symmetrically distributed fixing holes 1e on both sides, and a recessed arc groove 1d on the front plate of the mounting frame 1. The mounting frame 1 has an insertion cavity 1a that penetrates the top frame surface of the mounting frame 1. The front plate of the insertion cavity 1a has a through cavity that communicates with the insertion cavity 1a, and a transparent plastic plate 11 is fixedly embedded in the through cavity. The rear plate of the insertion cavity 1a has several evenly distributed mounting grooves 1b, and each mounting groove 1b is provided with a pressing status indicator 2. The pressing status indicator inserted into the insertion cavity 1a is firmly pressed against the transparent plastic plate 11 by the pressing component 2.
[0030] The abutting component 2 includes a sliding post 21, which is installed in the mounting groove 1b and slidably connected to the mounting groove 1b. A rotatably connected steel ball 22 is installed in the hemispherical groove opened at the head of the sliding post 21. The steel ball 22 abuts against the inner surface of the transparent plastic plate 11. A spring 23 is provided in the mounting groove 1b. One end of the spring 23 is fixedly connected to the inner wall of the mounting groove 1b, and the other end of the spring 23 is fixedly connected to the insertion end of the sliding post 21.
[0031] It should be noted that when installing the status indicator on the instrument, rivets (or screws) are first used to pass through the fixing holes 1e of the mounting frame 1 to fix it in the mounting holes of the instrument. Then, the status indicator is inserted into the insertion cavity 1a from the top opening. Since the steel ball 22 is abutting against the inner plate surface of the transparent plastic plate 11 in the initial state, when the status indicator is inserted into the insertion cavity 1a, as the status indicator slides down the insertion cavity 1a and abuts against the spherical surface of the steel ball 22, the steel ball 22 pushes the sliding column 21 to slide along the mounting groove 1b and compress the spring 23. Therefore, the status indicator is completely inserted into the insertion cavity 1a. At this time, all the steel balls 22 are pressed firmly against the transparent plastic plate 11 by the elastic force of the spring 23 to fix it (the part of the status indicator corresponding to the concave arc groove 1d is exposed).
[0032] When the status indicator needs to be replaced, the staff presses the status indicator at the concave groove 1d with their fingers and slides the status indicator along the insertion cavity 1a to quickly remove the status indicator from the insertion cavity 1a. Then, the new status indicator is installed into the mounting frame 1.
[0033] In this application, the mounting frame 1 is firmly fixed to the instrument installation area for the first time, and then the status indicator is installed into the insertion cavity 1a of the mounting frame 1 by insertion. The entire status indicator installation process only takes a few seconds, which greatly improves the replacement efficiency. It is especially suitable for installation scenarios with dense instruments or limited space. Several evenly distributed abutment parts 2 can form multi-point uniform pressure on the status indicator, ensuring that the status indicator is tightly attached to the transparent plastic plate 11 and avoiding displacement of the status indicator due to vibration and impact. At the same time, this structure does not require holes to be made on the status indicator, avoiding problems such as rivet hole enlargement (or thread stripping) and shell damage when replacing the status indicator later. It can be repeatedly disassembled and used, and the long-term reliability is significantly improved.
[0034] The transparent plastic plate 11 on the front panel of the insertion cavity 1a provides effective physical protection for the status indicator, preventing damage caused by collisions and friction, while not affecting the staff's ability to read the status indicator information. The transparent plastic plate 11 is made of high light transmittance and high wear resistance polycarbonate (PC) sheet, and its surface is treated with an anti-scratch coating (such as nano silica coating) to improve surface hardness and wear resistance and extend service life.
[0035] Furthermore, the bottom frame of the mounting frame 1 is provided with several drainage holes 1c that are interconnected with the insertion cavity 1a. The drainage holes 1c can quickly drain the water that has accumulated in the insertion cavity 1a.
[0036] Furthermore, a rubber pad is fixedly fitted to the back of the mounting frame 1, which reduces the pressure between the mounting frame 1 and the instrument mounting area.
[0037] In addition, to eliminate the potential risk of spring 23 rusting and losing its elasticity due to contact with water, spring 23 is made of stainless steel or titanium alloy to improve corrosion resistance. At the same time, a polytetrafluoroethylene (PTFE) coating is applied to the surface of spring 23 to enhance its rust prevention ability.
[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
